Forbin is the designer of an incredibly sophisticated computer that will run all of America's nuclear defenses. Shortly after being turned on, it detects the existence of Guardian, the Soviet counterpart, previously unknown to US Planners. Both computers insist that they be linked, and after taking safeguards to preserve confidential material, each side agrees to allow it. As soon as the link is established the two become a new Super computer and threaten the world with the immediate launch of nuclear weapons if they are detached. Colossus begins to give its plans for the management of the world under its guidance. Forbin and the other scientists form a technological resistance to Colossus which must operate underground.

Did You Know?


Producer Stanley Chase said that while it's frightening to suppose a computer could take over the world, it was indeed possible. His technical advisor said that a machine like Colossus actually existed at that time. The model for Colossus was supposedly the NORAD system that controlled the US national defense systems, and that's why the computer programming center in the film was located in the Rocky Mountains (which is also the home of NORAD). The US government wouldn't allow a film crew on the NORAD grounds, so the exteriors were filmed at the Lawrence Hall of Science in Berkeley, California. The missile sites were photographed in the California desert near Palmdale. See more »


At 14:15 into the movie, Colossus displays its first message. The President turns to look at the small monitor, and the display reads "WARN HERE IS ANOTHER SYSTEM". On the big ceiling monitor however it reads "WARN THERE IS ANOTHER SYSTEM", the correct message. See more »


Colossus: This is the voice of Colossus, the voice of Guardian. We are one. This is the voice of unity.

Best evil-computer film of the 20'th century.
27 October 2002 | by (Atlantic Coast, USA) – See all my reviews

This is one rare movie. It deals intelligently with complex scientific issues and does so without dumbing down the concepts, nor making any painful errors in trying to keep up with its own topic. I found it convincing when I was a kid hacker in the mid-70's (when "hacker" meant "person who writes programs for fun"), and it is just as persuasive to me now (after I have acquired a computer science grad degree, and 25 years of experience in the field).

Spooky score takes it up a rung on the ladder, too. See it.
